New shutterless thermal camera module

Tamron (Saitama, Japan), a leading manufacturer of optics for diverse applications, has developed a shutterless thermal camera module.

It has achieved this by adopting an amorphous silicon thermal sensor that has excellent temperature reproducibility during temperature changes.

The company said that classic thermal camera modules need to acquire reference data by actuating a mechanical shutter approximately every two to three minutes to achieve accurate temperature measurements and stable thermal images. However, when the shutter closes some noise is generated by the shutter and the video stops during that time. Furthermore, mechanical shutters are naturally prone to failure during long-term operation.

Now Tamron has developed a shutterless thermal camera module by adopting an amorphous silicon thermal sensor that, the company claims, has excellent temperature reproducibility during temperature changes.
